Method and device for storing equalization settings in active loudspeaker

Abstract

The invention relates to a method and a loudspeaker for storing equalization settings in an active loudspeaker including a loudspeaker cabinet, at least one driver connected to the cabinet and an amplifier electronics including an equalizer, in which method the loudspeaker is calibrated in controlled conditions for forming factory calibration parameters for controlling the equalizer, the factory calibration parameters controlling the equalizer are stored in the amplifier electronics. In accordance with the invention the factory calibration parameters are also stored in a memory fixedly mounted to the loudspeaker.

       5. The method in accordance with  claim 1 , wherein the memory is connected with the amplifier electronics with a serial cable. 
     
     
       6. The method in accordance with  claim 1 , wherein the memory is connected with the amplifier electronics wirelessly. 
     
     
       7. The method in accordance with  claim 1 , wherein the memory interface is used for controlling other functions of the loudspeaker electronics. 
     
     
       8. The method in accordance with  claim 1 , wherein the memory is a tag like 2d barcode or RFID-tag including the factory calibration parameters. 
     
     
       9. The method in accordance with  claim 1 , wherein the memory is a tag like 2d barcode or RFID-tag including a link to factory parameters. 
     
     
       10. A loudspeaker comprising;
 a loudspeaker cabinet, 
 at least one driver connected to the cabinet, 
 amplifier electronics including an equalizer with a memory for storing equalization parameters, the equalization parameters comprising at least one of:
 filter coefficient values 
 factory correction settings for equalizing filters, and 
 
 an additional memory fixedly mounted to the cabinet and having telecommunications capabilities with the amplifier electronics for storing and reloading backup values of the factory calibration. 
 
     
     
       11. The loudspeaker in accordance with  claim 10 , wherein the memory is fixedly mounted to the loudspeaker cabinet. 
     
     
       12. The loudspeaker in accordance with  claim 10 , wherein the memory is fixedly mounted to at least one driver. 
     
     
       13. The loudspeaker in accordance with  claim 10 , wherein the loudspeaker includes a first memory including at least information about the loudspeaker cabinet and at least one second memory including at least information about a driver. 
     
     
       14. The loudspeaker in accordance with  claim 10 , wherein the memory is connected with the amplifier electronics with a serial cable. 
     
     
       15. The loudspeaker in accordance with  claim 10 , wherein the memory is connected with the amplifier electronics wirelessly. 
     
     
       16. The loudspeaker in accordance with  claim 10 , wherein memory interface is used for controlling other functions of the loudspeaker electronics. 
     
     
       17. The loudspeaker in accordance with  claim 10 , wherein the memory is a 2D tag, 1D barcode or RFID-tag including the factory calibration parameters. 
     
     
       18. The loudspeaker in accordance with  claim 10 , wherein the memory is a 2D tag, 1D barcode or RFID-tag which includes a link to the factory calibration parameters. 
     
     
       19. A method for storing equalization settings in an active loudspeaker including a loudspeaker cabinet, at least one driver connected to the cabinet and an amplifier electronics including an equalizer, in which method
